The self-styled sheik behind a siege at a Sydney cafe had been charged as an accessory to murder and with multiple sexual offenses. He also harbored deep grievances against the Australian government and had found little kinship in the city's large Muslim community, where he was seen as deeply troubled.

Man Haron Monis, an Iranian refugee described by those who knew him as a loner, was killed early Tuesday after heavily armed police stormed the Lindt Chocolate Cafe to end a 16-hour hostage drama that made global headlines.

Last year Monis was charged as an accessory to the stabbing murder of his ex-wife, who was set alight in a Sydney apartment block. He was charged this year with more than 40 counts of sexual or indecent assault against women in Sydney, according to court documents.
